An EPS Bearer is a logical tunnel that carries traffic with a specific Quality of Service. It acts like a "virtual pipeline" from the user device (UE) to the P-GW. There are two main types:
The is what makes high-speed, low-latency mobile broadband possible. From attaching a device to seamless handovers—it all lives here.
The P-GW connects the LTE network to external packet data networks, such as the public internet or an IP Multimedia Subsystem (IMS) for Voice over LTE (VoLTE). It allocates IP addresses to mobile devices and enforces Quality of Service (QoS). Home Subscriber Server (HSS) An EPS Bearer is a logical tunnel that
The MME sends a to the S-GW over the S11 interface. The S-GW passes this to the P-GW over S5/S8. The P-GW releases the allocated IP address, terminates policy enforcement with the PCRF, and returns a Delete Session Response . Step 3: Acknowledgment and Release
The MME notifies the HSS of the user's location via an Update Location Request . The HSS responds with the subscriber's profile data, specifying authorized Access Point Names (APNs) and QoS profiles. Step 4: Session Creation (Control Plane) From attaching a device to seamless handovers—it all
The EPC framework provides converged voice and data services, treating both as IP applications. It provides essential services such as mobility management, session management, and data services for mobile phones and data terminals.

When a device powers down or loses network access, it gracefully disconnects to free up core network resources. The UE sends a Detach Request to the MME.
Understanding call flows is crucial for debugging and optimization. The following are the most fundamental procedures in an LTE network.
